Summary
Waldenström's macroglobulinemia (WMG) rarely involves the airways. This case highlights endobronchial tumor cell invasion causing airway narrowing and respiratory symptoms in WMG patients.
Area of Science:
- Hematology
- Pulmonary Medicine
- Oncology
Background:
- Waldenström's macroglobulinemia (WMG) is a rare lymphoproliferative disorder.
- Pulmonary involvement in WMG is documented, but typically involves interstitial or pleural spaces.
Observation:
- A unique case of WMG presented with endobronchial tumor cell infiltration.
- The tumor invasion led to significant narrowing of the patient's airways.
Findings:
- Endobronchial involvement is a previously undescribed manifestation of Waldenström's macroglobulinemia.
- Tumor infiltration of the bronchi can cause obstructive respiratory symptoms such as coughing and wheezing.
Implications:
- This finding expands the spectrum of pulmonary manifestations of WMG.
- Clinicians should consider endobronchial WMG in the differential diagnosis of unexplained airway obstruction and respiratory symptoms.
